Check Digit Verification of cas no
The CAS Registry Mumber 1188-33-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,8 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1188-33:
(6*1)+(5*1)+(4*8)+(3*8)+(2*3)+(1*3)=76
76 % 10 = 6
So 1188-33-6 is a valid CAS Registry Number.

Process for preparing diphenylamines
-
, (2008/06/13)
A process is described for preparing diphenylamines of the formula STR1 by oxybromination of a phenol ether compound using elemental bromine in the presence of hydrogen peroxide and of a catalyst to give a brominated phenol ether compound which is subsequently reacted with a formanilide compound to give the compound of the formula (1). The oxybromination reaction is a regioselective, environmentally friendly and cost-efffective method of preparing brominated aromatic compounds. The diphenylamines of the formula (1) are industrially useful intermediates for the production, for example of dyes, and in particular of color formers of the fluoran type for pressure- or heat-sensitive recording systems.
